Abstract
The utility model relates to a light field heat collection system for a tower type solar energy thermal power plant, belonging to the technical field of solar energy power generation, comprising a mirror field formed by condensers, wherein inside the mirror field there are provided mirror towers, the mirror towers are connected with generator sets through pipes, the mirror field is divided into a plurality of areas and provided with a plurality of mirror towers, and the mirror towers are arranged at the south side of different areas of the mirror field. The light field heat collection system for a tower type solar energy thermal power plant employs a distributed mirror tower design, and the condensers of different areas in a condenser array respectively condense light towards different mirror towers, thereby greatly reducing the height of each mirror tower, simultaneously reducing light spot deviation on a heat collector due to remote light condensing, and increasing heat collection effect.
Description
Technical field:
The utility model relates to the solar energy generation technology field, is specifically related to the light field collecting system of a kind of tower type solar energy thermal power generation power plant.
Background technology:
In existing solar utilization technique, it should be the tower type solar thermal technology that the U.S. and Israel begin to research and develop the seventies in last century that the sun power that cost is minimum utilizes mode.Its used material is the glass planar mirror, and the cost of material is extremely low, and it is with good conditionsi fully the ultra-large sun power that utilizes.Tower-type solar thermal power generating system is mainly by condenser system, inhales, heat-exchange system, and heat reservoir and electricity generation system four parts composition, wherein condenser system comprises catoptron, supporting construction, gearing and tracking control system.A large-scale tower solar power plant needs thousands of cover condenser systems, and catoptron is arranged according to certain rules and formed in the condenser system, and controls catoptron from the motion tracking sun by computer, and whole thermal-arrest light field is taken up an area of can reach several sq-kms.The heat collector of traditional tower power plant is placed on the high tower, and high tower is built mirror battle array central authorities or southern side in, to accept the sunshine of reflection mirror array emission.When sunlight project energy collector be absorbed be transformed into heat energy after, the medium that just flowing in the heating coil produces steam.
The outstanding advantage in tower power station is that light concentrating times is high, and the heliostat number in the array is many more, and its optically focused is bigger than more, and the heat-collecting temperature of receiver is also just high.The concentration of energy process is to lean on reflection ray one step completed in addition, has saved too much loop design, and method is simple and direct effectively.And also there are some inevitable shortcomings in tower power station: the one, because the light field floor area is huge; Guarantee that Jing Chang still has the reflection angle can reflected sunlight apart from the catoptron of Jing Ta farthest; This just requires the mirror tower height degree can not be low excessively; Usually be not less than 30 meters, the height of tower is high more just to make that transporting heat exchange medium expends more multipotency.The 2nd, because reflected light receives inevitable disturbance, make the hot spot that projects on the mirror tower heat collector deviation can occur, the flare deviation will be difficult to control when catoptron is far away apart from Jing Ta.
The utility model content:
The utility model technical matters to be solved is to provide a kind of mirror tower height degree low; The light field collecting system of the tower type solar energy thermal power generation power plant that Heat-collecting effect is good, this light field adopt distributed Jing Ta design, and a plurality of thermal-arrest towers are arranged in the condenser array; Condenser in the mirror field is respectively to a plurality of Jing Ta difference optically focused; The height of each Jing Ta needn't be very high like this, in addition because catoptron apart from mirror tower close together, makes the deviation of the flare of reflected light on mirror tower heat collector reduce greatly.
The utility model technical matters to be solved adopts following technical scheme to realize:
The light field collecting system of a kind of tower type solar energy thermal power generation power plant, it is characterized in that: comprise the Jing Chang that is made up of condenser, mirror is provided with Jing Ta in the field, and Jing Ta connects genset through pipeline, and said Jing Chang is divided into a plurality of zones, and is provided with a plurality of Jing Ta.
Said Jing Ta is arranged on the southern side in the zones of different of mirror field.
In the mirror field, select suitable position, orientation, design a plurality of Jing Ta.For example, for the Northern Hemisphere, Jing Ta should design the southern side in mirror field zones of different.The height of each Jing Ta is by the condenser number decision to this mirror tower optically focused, and the condenser reflected light that requires to guarantee the farthest can generally, can be reduced to 10 meters or lower with mirror tower height degree through design to the heat collector optically focused of this Jing Ta.So also make the energy that heat exchange medium is transported on the tower to be consumed reduce.
Whole Jing Chang is divided into different zones accordingly, and the condenser mirror in the same area is to same mirror tower optically focused, and the condenser of zones of different is to different mirror tower optically focused.This tracker that requires computerized control system can control zones of different is accomplished this operation.
What particularly point out is that the division of condenser array is not what fix in the mirror field.As required, the catoptron of the condenser array of zones of different can be turned angle, to apart from other mirror tower optically focused in the OK range.Can regulate the condenser tower according to factors such as the variation of sun altitude and weather like this, to improve the collecting efficiency of whole Jing Chang.
The utility model adopts distributed Jing Ta design, and the condenser of zones of different is respectively to different mirror tower optically focused in the condenser array.Greatly reduce the height of each Jing Ta like this, the deviation of hot spot has improved Heat-collecting effect on the heat collector that has reduced simultaneously to cause owing to remote optically focused.

Fig. 1 is the structural representation of the utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with specific embodiment and diagram, further set forth the utility model.
As shown in Figure 1; The light field collecting system of a kind of tower type solar energy thermal power generation power plant comprises the mirror field of being made up of condenser 24, is provided with mirror tower 1 in the mirror field 4; Mirror tower 1 connects genset 3 through pipeline; Mirror field 4 is divided into a plurality of zones, and is provided with a plurality of mirror towers 1, and mirror tower 1 is arranged on the southern side in 4 zoness of different of mirror field.
